  2. Change the VSAN attribute to 1.
  3. Add a secondary SAN boot target.
  4. Set the boot LUN to 0.

Answer(s): B



Refer to the exhibit.



A Cisco ACI fabric experiences a packet drop for high-priority signaling traffic. Which configuration protects high-priority queues from dropping?

  1. Change the scheduling algorithm to strict priority.
  2. Change the admin state to disabled.
  3. Change the scope to fabric-wide PF
  4. Change the congestion algorithm to WRE

Answer(s): A

Explanation:

Strict Priority Scheduling ensures that high-priority traffic is always served before other lower-priority traffic, avoiding packet drops in high-priority queues. In contrast, weighted round-robin (WRR) shares bandwidth between all queues, which can lead to drops for high-priority traffic if the bandwidth is exhausted.
Changing the scheduling algorithm from Weighted Round Robin (WRR) to Strict Priority prioritizes the high-priority queues and prevents drops for critical traffic like signaling.
